Cardano Node 11.0.1 dey push Mainnet readiness toward Van Rossem upgrade

Cardano infrastructure teams dey continue prepare for Van Rossem, the Protocol Version 11 hard fork wey dem name to honor Max van Rossem. The update now dey focus on node adoption, tooling compatibility and the final governance path wey must happen before any mainnet enactment fit take place.

cardano-node 11.0.1 Supports the PV11 Hard Fork Path

cardano-node 11.0.1 come out on May 5, 2026 as the first node version wey support the PV11 intra-era hard fork. The release go enable Cardano infrastructure to move toward Protocol Version 11 once dem submit the required hard fork governance action, SPOs, DReps and the Constitutional Committee vote am, and dem enact am on-chain.

The release also move cardano-api and cardano-cli enter the 11.0 series, push the experimental hard fork target toward Protocol Version 12 and add HTTPS support for EKG and Prometheus metric servers inside cardano-tracer. E still introduce new Linux dependencies wey connect with LSM capabilities, including liburing, protobuf-compiler and snappy-c.

Intersect don talk before say node v11.0.1 remain the mandatory upgrade path for infrastructure providers to pass the Protocol Version 11 hard fork boundary. Operators wey still dey older node versions, including node 10.7.1, no go fit progress pass that boundary once the mainnet hard fork don enact.

Van Rossem dey move forward after PreProd enactment

Van Rossem na the name wey Cardano dey use for the Protocol Version 11 hard fork. Intersect report say the Van Rossem hard fork succeed for PreProd on June 10, wey move the process from testnet activation enter ecosystem readiness and mainnet planning.

The next step still tie to governance. Intersect talk say the Hard Fork Working Group mainnet go/no-go decision bin schedule for June 15, and Technical Steering Committee plus Civics Committee reviews support submission readiness. As of June 16, no public official source don confirm the go/no-go result, mainnet governance action ID or confirmed mainnet enactment date.

That distinction mean say the current story still dey for readiness phase. cardano-node 11.0.1 dey prepare infrastructure for PV11, but the node release no be the same thing as mainnet enactment. Van Rossem self different from Ouroboros Leios, wey belong to Cardano scaling roadmap, and from the Plutus Cost Model parameter update, wey be separate governance parameter action.

Mainnet readiness depend on node adoption and tooling compatibility

Intersect June 12 update report say adoption of node v11.0.1 dey increase across the Cardano ecosystem. According to the update, PoolTool show say 52 percent of nodes self-report v11, while 76 percent of block production for the current mainnet epoch dey happen on Protocol Version 11. Cexplorer report say more than 84 percent of blocks wey dem produce over the previous five days come from v11 nodes.

The readiness path also include supporting infrastructure. Intersect don identify DB-Sync v13.7.1.0 as the recommended version for ecosystem participants wey dey prepare for Van Rossem, while Ogmios v6.14.0.2 and Kupo v2.11.0.1 still be supported options through Intersect-maintained forks as dem dey pursue upstream-compatible releases.

For SPOs, exchanges, wallets, dApp teams and indexer operators, the current phase na operational compatibility window. Testing for Preview and PreProd still focus on transaction construction, script validation, indexer behavior, wallet support and toolchain readiness. Until dem publicly submit a mainnet governance action and confirm an enactment date, Van Rossem remain a mainnet readiness story wey center around node adoption, infrastructure checks and the final governance path to Protocol Version 11.
